It will help identify ways in which policy and preventive programs can contribute to improving health in mid to later life particularly among disadvantaged Australians. We will explore in detail social, economic and environmental factors in 100,000 people aged 45 and over; this will be the largest study of its kind ever undertaken in Australia. We will examine the relationship between these social, economic factors, and lifestyle factors such as smoking, physical activity, environmental and obesity. This will enable us to identify where programs and policies should be directed to most rapidly improve the health of disadvantaged Australians.Read moreRead less
The impact of leader financial rewards on work group functioning. This project aims to investigate when and why organisational leaders’ financial rewards improve or undermine social group functioning. Leaders’ pay has increased markedly in recent years, fuelling debate about the impacts on organisational functioning.

This project aims to investigate when and why organisational leaders’ financial rewards improve or undermine social group functioning. Leaders’ pay has increased markedly in recent years, fuelling debate about the impacts on organisational functioning. While some studies have found high leader rewards have positive effects on group outcomes, others found negative or no effects. Expected outcomes include data on the effects of leader rewards on social identification with the group and contribution to collective goals, that will help policy-makers design reward systems that optimise functioning. This has the potential to significantly benefit Australian business and organisations to facilitate high-functioning groups and improve productivity.Read moreRead less
The Older Australian Twins Study (OATS) Of Healthy Brain Ageing And Age-related Neurocognitive Disorders

Funding Amount
$940,960.00
Summary
Ageing is associated with cognitive decline and dementia. It is still not completely understood what relative contributions genes and environment play in these. This project is an extension of the Older Australian Twins Study to examine genetic and environmental factors associated with late life brain changes and dementia, and will establish an internationally significant cohort for novel discovery.
Cancers of the skin are the most common tumours in humans, and their diagnosis and treatment impose the largest costs on Australia’s cancer budget. While much has been learned about the roles of sunlight and skin type as risk factors for skin cancer, relatively little is known about the genes conferring risk. This study will compare the genetic profiles of over 6000 patients with skin cancer to 3000 people without skin cancer to pinpoint the genes responsible for skin cancer.
Molecular Regulation Of CRH Gene Expression In The Human Placenta

Summary
Approximately 70% of infant death is a result of premature birth. Preterm delivery occurs in 6-10% of pregnancies, and there has been no reduction in this rate in the last 30 years. This is largely because we remain ignorant of how normal and preterm birth is controlled. Understanding the physiology of human pregnancy is a critical step in the development of ways to detect and prevent preterm birth. Our group has demonstrated a link between production of a hormone (corticotropin releasing hormon ....Approximately 70% of infant death is a result of premature birth. Preterm delivery occurs in 6-10% of pregnancies, and there has been no reduction in this rate in the last 30 years. This is largely because we remain ignorant of how normal and preterm birth is controlled. Understanding the physiology of human pregnancy is a critical step in the development of ways to detect and prevent preterm birth. Our group has demonstrated a link between production of a hormone (corticotropin releasing hormone, CRH) in the placenta and the length of time the baby is carried in the mother. In women who will deliver prematurely the rise in CRH production occurs earlier and more rapidly, while in women who deliver late the rise occurs more slowly. This work has led to the concept of a biological clock that determines the length of time the fetus will be carried by the mother before birth, and in which production of CRH in the placenta plays a central role. We have been studying how the CRH gene is controlled in placental cells. We have discovered some regions in the DNA of the CRH gene which have important roles in controlling how much CRH is made by the placenta. The experiments described in this project will determine the molecular mechanisms that control the production of CRH in the human placenta. This will be done by examining the DNA sequences involved in controlling the CRH gene and by identifying the proteins that actually perform the regulating functions that result in either increased or decreased amounts of CRH being produced by the placenta. This important information will help us better understand how normal and preterm birth is controlled, and from that knowledge new ways to detect and prevent premature birth can be developed.Read moreRead less
Improving Outcomes For Children With Common Developmental Conditions: Identifying Risk And Protective Factors And Developing Targeted Interventions

Summary
Attention Deficit Hyperactivity Disorder (ADHD) and language impairment (LI) are both highly prevalent and associated with mental health difficulties. This research will investigate 1) risk factors for poor versus better mental health, academic and social outcomes in children with ADHD and LI and 2) the development and piloting of interventions targeting these factors. This research will indicate avenues for new methods of intervention and prevention for children with ADHD and LI.
A Behavioural Intervention For The Adoption & Maintenance Of Physical Activity In Type 2 Diabetes

Summary
For people with type 2 diabetes (T2DM) it is essential that blood glucose levels are managed well to reduce the risk of developing complications. Physical activity is essential for maintaining glucose levels because it helps make the muscles use glucose more effectively. In particular, being active through strength training not only improves blood glucose levels, but can be very effective for maintaining good physical functioning, which is known to be reduced by having T2DM. This study builds on ....For people with type 2 diabetes (T2DM) it is essential that blood glucose levels are managed well to reduce the risk of developing complications. Physical activity is essential for maintaining glucose levels because it helps make the muscles use glucose more effectively. In particular, being active through strength training not only improves blood glucose levels, but can be very effective for maintaining good physical functioning, which is known to be reduced by having T2DM. This study builds on our earlier research which demonstrated significantly improved blood glucose levels from a strength training program for older adults with T2DM. The strength training program is to be administered nationally in a research to practice trial (Lift for Life); however, the original research found that those who did not complete the program as it was intended (ie, poor adherence) did not show significant improvements in blood glucose levels. Furthermore, maintenance of strength training exercises after completion of the program was poor and resulted in return of blood glucose levels back to pre-starting levels. In people without diabetes, we have collected pilot data that shows that the use of behavioural strategies based on behavioural theories whereby each person's motivations and barriers are taken into consideration is more effective than the traditional one-treatment-fits-all approach. This study will evaluate the effectiveness of using behavioural strategies for improving adherence and maintenance to the Lift for Life strength training program (Enhanced L4L) for older adults with T2DM compared with the Standard L4L program. It will also follow-up participants 6 months later to determine the extent to which the changes in behaviour can be maintained. The study will provide information that will assist in the design, delivery and uptake of programs to improve treatment strategies in older adults with T2DM through the maintenance of healthier behaviours and lifestyles.Read moreRead less

Summary
Alzheimer’s disease (AD) begins many years before diagnosis and yet its aetiology is still poorly understood. The BRIDGET consortium aims to identify genetic variants that are associated with structural brain ageing, cognitive performance, and dementia risk in richly phenotyped international and Australian population-based samples. This work aims to provide crucial information on the molecular pathways leading to AD, potentially leading to improved health outcomes for our ageing population.
Do Exposures Before Conception Influence The Risk Of Asthma In Offspring?
Funder
National Health and Medical Research Council
Funding Amount
$688,586.00
Summary
Asthma and poor lung function are major causes of public health issues. Emerging evidence suggests adverse exposures even before the conception of a child may cause these conditions. The proposed project is part of an international study across generations to identify these factors. This study will provide novel evidence to guide interventions and identify studies to advance this area further. These original findings will be of great importance both nationally and internationally.
